This invention appertains to new and useful improvements 1n vermin destroying means for use on cultivating machinery.

for cultivator plows which will efficiently serve to apply poison to plants yto exterminate vermin thereon. Y j

Another important` object of the linven- 10 tion isto provide a poison applyin 'attachment for cotton cultivating plows or effec-y tively exterminating boll weevils.

During Vthe course of the following speciication, numerous other important objects and advantages of the invention `will readily become apparent to the reader.

In the drawings Figure 1 represents a side elevational view of the novel attachment on a cultivatory plow. v

Fig. 2 represents a vertical sectional view taken substantially on the llinen 2-2 of` Fig. 1.`

Fig. 3 represents a longitudinal sectional view through the reservoir. y

Fig. 4 represents a fragmentary vertical sectional view takenVV substantially on the linei-t of Fig. 2.

Fig. 5 represents a fragmentary vertical sectional view taken substantially on the line 5-5 of Fig. 4. n Y

Fig. 6 is a fragmentary vertical sectional viewthrough one of the poison applying units Fig. 7 is a perspective view of the clamp plate.

Fig. 8 is a 'fragmentary perspective viewv ofthe mixing paddle for the reservoir.

Referring to the drawings wherein like numerals designate lilreparts, it can be seen that the attachment is to be mounted on the beam 5 of a plow '6. -A hand type of plow is enclosed in Fig. 1, but 'of coursevarious other types of plows may have this novel v' attachment secured thereto without in any manner departing from the scope of this invention. Y

.In Fig. 2 it can be seen that'the attachment includes an'elongated upstanding post` `7 which is twisted at its lower portion as at 8 and bent laterally and downwardly as at 9., for disposition against one'side of the beam 5. A complementary strap 10 is secured to Y The principal object of the invention is 5 to provide a poison dispensing attachment 13-13 'at the intermediate portion of the reservoir 14. In this manner, the reservoir is supported ina position transverse of the beam 5 and as shown clearly in Fig. 8, the

bottom wall thereof is curved throughout -its entire longitudinal extent, the same'at its ends merging" with the plane `top wall thereof. l C Y This top wall has an Vopening atV the intermediate portion thereofand an upstanding flange 15 ysurrounds thisopening. lllhe rearwardly disposed upper end of the post 7 has the upper yend of andepending arm 16 secured thereto, the lower end of which is twisted asiat 17 and has a paddle blade 18 secured thereto. The paddle bladeV is provided with openings 19 therein through which tlief'poison mixture within the reser` Voir may flow, during the rocking motion ofthe reservoir while the plow isvin oper ation.

It can also be seen that yan elongated bar 2O is secured atfits intermediate portion to the laterallyy disposed-portion of the post-7',l with each portion beyond-the said laterally bent portion of the post disposed downwardly, to terminatelin close spaced relation with respect to the top wall of the reservoir, when the reservoir is in a level position.

The under side of the bar 20 at each end thereof `is provided with a bumper block 21 i of some suitable resilient material for en-v gagement with'the reservoirto limit the ,.1

The bottom curved wall of the reservoir is provided at its intermediate points with a pair of internally threaded sockets 23, each of which receives the upper externally threaded end of a nipple 24. It will also be noted that the top wall of the reservoir irnmediately above each socket 23 is provided with an opening, surrounded by acollar 25.

ASlidably and rotatably disposed through each of these collars 25 is an elongated shaft 26, provided with a lnurl'ed: head 27 at itsY upper end. The lower end of each of these shafts 26 is hollow and provided with external threads 28, whereby this end of the shaft may be flared into a corresponding pocket 23.

Asis clearly shown in. Fig. 5, the threaded portion 28 of each shaft `26 is provided with an: obliquely disposed slot (that is oblique with respect tothe longitudinal axis thereof), denoted by numeral 29, and obviously by feeding the. shaft 26 outwardly,

more and more ofthe slot 25 may be exposed to reg-ulate the amount of poison liquid to fbe dispensed through the underlying nipple As is clearly shown in Fig. 2, a pair of cross bars 30-30 are employed for supporting the poison distributing units, each denoted generally by numeral 3l.

The inner end of each of these-bars is provided with longitudinally spaced openings 32, and these perforated ends of the bars are disposed in overlapping relation across the lower portion of the post 7 and between the spaced legs 33 on the clamp plate 34. v

This clamp plate is provided with a central opening 35. By disposing a bolt thru.

registering openings 32 of the bars 30-30 and thru the opening 35 of the clamp plate, and applying a nut thereto, these parts may be all firmly secured together in the position shown in Fig. 2. Y

Each of the portion distributing units 31 includes a trough 36 supported by a depending arm 37 at the outer end of the corresponding bars 30. The trough 36 is providedV with'a wall 38 at each lend thereof, so that the trough may receive and retain any' of the poison liquids `which fall.V fromk the strands '39 forming the applicator.

This applicator is tied together as at 40, and at as many points as is desired', and as clearly disclosed in Figs. 2 and 6, the .upper ends of the strands are disposed around the lower end of the corresponding hose 41, and secured thereto by the clamp rings 42, Vcarried by the arms 37. i

The' upper end of each of theV hose 41 receives the lower end of its corresponding nipple 24', so that liquid discharging through the corresponding nipple 24 will flow through the particular hose to the corresponding Yapplicator. The lower end of the applicatorhas Vliquid therein against the paddle 18 will result in the continuous mixing of the liquid to prevent any sediment taking place.

It is to be understood that while the foregoing specification has been definite, the same has been explained in specific details, and it is to .be understood that numerous changes in the shape, size, vand materialsA may be resorted to without departing from the spirit and .scope of `the invention as claimed hereinafter. Y A l e Having thus described our invention, what we claim as'new is: r v .l 1. A poison applicator of the class described comprisinga vehicle carried reservoir, a vehicle carried trough having ,anVV

opening in its bottom, an upright on the trough, a horizontal supporting member connected with the upright, a plurality of strands havingtheir upper ends connected with the supportingmember and passing through the hole in the trough, and a tube leading from the `reservoir into-the upper end of the group of strands- 2. A poison applicator of the class described comprising an upright, means for attaching the lower endI oftheV upright to an agricultural implement, the upper end of the upright being of inverted U-shape,.

a reservoir having trunnions at its ends whichV are journaled in the limbs of the U- shaped part, a member depending from the bight of the U-sliaped part into'the reser-V voir, a cross piece having holes therein connected 1n the `lower ,end of said member, a-

cross bar connected to the lower part of thev upright, a trough'supported at each endof the cross bar, and having a hole in its bot-p torn, agroup of strands of fabric passing through the holein eachtrough, means for` connecting-theupper end; of Yeach group'to the cross bar, a tube connecting the reservoir to the top of each Lgroup of strands, the lower end of each tube extending'to the upper end of each group andV valve means forV controlling the flow of liquidgfrom the reservoir into each tube.

In testimony whereof weaffixy our signatures.
